PERCOLATOR.

Patented Jan. 18, 1916.

Application filed August 5, 191%. Serial No. 855,314.

' To all whom it may concern Be it known that I, ARTHUR ZIMMERMANN, acitizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Percolators, and do hereby declare the following to be afull, clear, and exact description'of the invention, such as will enableothers skilled in the art to which it appertains to make anduse thesame. v

This invention relates to percolatorsand more particularly to that typewherein the parts thereof which receive and confine the liquids are madeof non-metallic substances.

An object of this invention is to provide an improvedmeans forconnecting the infusor and spout so as to receive a strainer and toprovide an improved means for mounting the neck of the spout in the neckof an urn. Q

Further objects will be apparent in the following specification,appended claims and drawings in which,

Figure 1 is a side elevation of the percolator made in accordance withthis inven- A tion, showing parts broken away for the sake of clearness,Fig. 2 is an enlarged sectlonal view of a portion of the device, Fig. 3is a horizontal sectional view as on the line 33 of Fig. 1, Fig. 4: is avertical sec- 7 tional view as on the line 44 of Fig. 3,

Fig. 5 is a vertical sectional view through a portion of the deviceshowing a modification and,- Fig. 6 is a sectional view j through afurther modified form.

.It has been" proven that coffee made in a percolator free from metallicparts is superior to cofi'ee which in its making is subjected to thechemical action resulting from the contact with metallic substances. Inthe production of an apparatus in which no similar reference numeralsindicate similar parts throughout the several views, and which show theseveral features of this type of percolator. The device is notrestricted to the specific form shown but will pref-.

erably be made in accordance therewith. There is shown a base 10 havinga standard 11 rising therefrom to which a. handle 12 may be secured. Abracket 13 is supported by said standarda'nd this bracket termi 'natesin the split semi-circular members 14 and 15 which are hinged as at 16to allow the member 15 to be swung to the desired position. The member15 terminates on a tapered tongue or e itension 17 which has its faceserrated as at 18 to conform with a similar face on the opposite .wallofthe bracket 13. When the member 15 is swung to grip the neck of an urn,a slide 19 may he slid to cause enlargements thereof to engage theserrated faces 18 and thereby hold the members 14 and 15 in bindingrelation with the necessary resiliency to allow for the expansion of theneck of the urn. The members 14;,and 15 support resilient pads 20therein which are held in place by the flanges 21 which engage under theinturned edges of the members 14 and 15 as shown in Fig. 4, and thesepads have further provision, of the flanges 22 which overlap theinturned edges of the members 14 and 15 to prevent any metallic contactwith the glass of which the urn will preferably be made.

Supported by the bracket 13 is an urn 23 which has a reduced neck to begripped by the members 14 and 15 and supported by the base 10 under thisurn is a lamp or burner 2 f. The upper end of the neck of said urnflares outwardly as at 25 to receive the flaring neck of a spout 27which latter carries on the outside thereof a rubber or similar collar26 to .establisha gri ping action between the neck of the urn an theneck of the spout 27. The spout 27 is provided with an external bead 28which holds the collar 26 against longitudinal movement on the spout andthe neck ofthe spout will preferably,

conform with the flared portion 25 of the urn,so that the desired sealmay be established without forcing the collar 26 into the 'neck of theurh as the rubber collar will bind in the neck of the urn when it isdesired to separate the parts of the device after usage.

v The neck of the spout has, an upwardly facing shoulder 29 surroundedby an internally threaded flange orwall 30 extending above the shoulder.Upon the shoulder .29 1S placed a strainer comprising. a perforated'diaphragm 31 over'which a strainer cloth I 32 has been placed and aalnst whichrub her collars or gaskets 33-; fave been mam; bled as shown.Then the lower end of the vneck 3410f an'infusor 35 is brought to bearupon one of the gaskets 33 by the threaded fitting top 36 which permitsthe egress andengagement of the neck 34 with the flange 30. Saidinfu'sor35 is provided with a loose ingress of air as occasion may require.

In use, 'the urn 23 is filled to the desired point with water, afterwhich the spout 27 and infusor are connected with it as shown in Fig.land-the desired amount of cofl'ee' is placed in the infusor. Then theburner 24 may be lighted. to heat the water in the urn 23. When thetemperature of the water in the urn 23 has been raised sufficiently, theair and steam confined in the upper part of this urnforces the liquid upthrough the spoutv27 into the infusor where it extracts the flavor andessence froin the cofiee'. When enough water has been 'forced upwardlythrough the spout 27 to allow the passage of steam through said spout,"the burner 24 is removed from under said urn to allow the vapor in saidurn to contract and draw the coffee from the infusor 35 back into theurn 23, after which thespout may be removed and the coffee may be served.from the urn in the usual manner.

Fig. 5 which the shoulder 29 is surrounded by an upstanding wall orunthreaded flange 37 to receive a strainer member therein and the neckof the infusor has a plain exterior to'fit in the flange 37. At desiredpoints about the exterior of the infusor are lugs 39 into each of whicha clamp 40 may "spout 44 are integral and provided with a strainer inplace.

\ bead 45 formed thereabout to present an upwardly facing shoulder 29surrounded .by an upright wall 46. In this form the strainer member 31has the strainer fabric placed thereabout and is forced down withinshows a slightly modified form inclosely surrounding said collar; of astrainer I removably supported by said shoulder; and a strainer .clothoverlying the body of the strainer and passing around its edges incontact with said wall and-thence inward over said shoulder.

2. In'a percolator, the combination with an urn having a neck, a spoutalso having a neck whose upper end is formed with an upwardly facingshoulder surrounded by aupstanding wall, and packing between said necks;of a strainer resting at its edge upon said shoulder and inclosed bysaid wall an infusor having a reduced lowerend fitting closely withinsaid wall for holding the strainer in place, and means for detachably,connecting the infusor with the neck of the spout.

3. In a percolator, the combination with an urn havinga flared neck, aspout also having .a' flared neck whose upper end is formed with anupwardly facing shoulder' surrounded by an upstanding wall, a flaringrubber collarbetween'said necks, and a support for the urn; of astrainer resting at its edge upon said shoulder and inclosed by saidwall, gaskets above and below said strainer, an infusor having a reducedlower end fitting closely within said wall for holdingthe' strainer inplace,'and means for detachably connecting the infu'sor with the neck ofthe spout.-

4. In a percolator, the combination with an urn' having a flared neck, aspout also having a flared neck whose upper. end is formed with anupwardlv facing shoulder surrounded by an upstanding wall, a flaringrubber collar between said necks, and a sup- ,port for the urn; of astrainer resting at its edge upon said shoulder and inclosed by saidwall, an infusor having a reduced lower saidwall and onto the shoulderto hold the end fitting'clos'ely within said wall for hold- 4 The cloth32 serves to hold the diaphragm 31 in place and at the same timeprovides for the necessary expaIT- sion of the neck and the diaphragm 31when heated. The bead 45 serves to hold the rub-- ber collar 47 againstlongitudinal/movement in having said collar bead as shown:

Having thus described my invention- 1 partly surround said claim':

1. Ina percolator, the combination with" ing the strainerin place, lugsat intervals around the infusor, and clamps pivoted in.
